Standard-size aluminum piston for the Triumph 650 twin engine.

Being a standard-size piston, this is meant for a bore that hasn't been machined oversize, as opposed to the +.020 or +.040 pistons you'd reach for after a rebore. Aluminum is the expected material for a piston on these engines, nothing unusual there.
Given how thin our records are on this one, give the shop a call before you order so we can confirm it matches what your engine actually needs - bore size, ring configuration, and compatibility with your specific 650 twin all matter here.
